湖北嘉鱼－咸宁地区深部地质构造及成矿远景区的认识

DEEP GEOLOGICAL STRUCTURES AND METALLOGENIC PROSPECTIVE PROVINCE IN JIAYU - XIANNING AREA, HUBEI

笔者对研究区１：２０万重力、航磁和化探的系统资料进行处理，据新信息重新认识，判别深部地质构造。局部地区据钻探验证，从而为以下奠定了基础。１．推断基底断裂８条，盖层断裂１５条。基底断裂Ｆ１、Ｆ２、Ｆ３基本控制了本区的构造格架；２．圈定嘉鱼、山坡－贺胜、赤壁、桐梓岭、青峰（青石桥）等９个隐伏岩体。并对产出形态作了初步研究。３重磁资料新圈定的构造结合化探和地质成果预测铁、铜、金成矿远景区４处，油气成矿远景区３处。

Based on data of the graviational, aermagnetic and geochemical prospecting to a scale of 1 to 200000, the deep geological structures in the studied area have been re - considered and discriminated as following which have been corn firmed by geological drilling in some parts of this area.1.Eight basement faults and fifteen superficial faults have. been inferred among which the F1, F2 and F3 basement faults basiclly control the tectonic framework of this area.2.Nine concealed rock masses have been delimited such as Jiayu, shanpo - Hesheng, chibi,Tongziling, Qing Mountain (Qing shi Bridge) rock mass. ect, and their occurrence and morphology in space have been studied.3. In accordance with the structures delimited by gravitational and magnetic prespecting data, combined with the geochemical prespecting and geological results, four Fe, Cu and An metallogenetic prospective provinces and three oil and gas metallogenetic prospective provinces have been progonsticated
